Warnings posted at Ocean Beach after sewer overflow

Ocean Beach near Lincoln Way will remain posted Tuesday with signs warning against contact with the water following sewer overflows Dec. 23 and 24.

All of Ocean Beach and Fort Funston had been posted with warning signs, but bacteria levels have fallen enough that the signs will be taken down Tuesday, according to the San Francisco Public Utilities Commission.

Heavy rains had overwhelmed western San Francisco’s combined sewer system, which sends both stormwater runoff and wastewater from toilets and drains to the Oceanside water-treatment plant on the Great Highway. When too much water builds up in the system, the excess spills out from one or more locations onto the beach.
